Silversurfer, Actually my unspoken comment was ( I assumed) that you overpowered your skybolt. When I got my kit, a little pamphlet was included warning the flyer of the dangers of putting a 1.20 on the plane. It said that you must power down in a dive....etc....The .90 Saito is the lightest in it's class, and apart from 3d, I believe that it's going to be a real nice flyer I'm only going to use a 700mA battery, and standard servos. I'm also taking off the wheel pants for 2 reasons: 1st because I fly off of grass, and 2nd to save on some weight. I've had this engine on a 9.5 lb plane, and it had nice response in climbs, and I feel confident that my skybolt will be of similar weight. Sometimes I just don't fall into the group that believes that more engine is needed to overcome weight, while a lighter/less powerful motor might give better returns.
